The vet did x-rays, and got back to us...
We were given the option of either amputating her leg for about $1,000 or putting her to sleep, on the low end of things. (The high end was a $2,000 operation to try and save her leg.) Even with the credit I applied for, $1,000 might as well be a million.
We chose a different option, instead - we've brought her home, and are going to try and take care of her the best we can, because we can't afford the amputation, and we don't want to put her to sleep over a hurt leg.
We can use all the prayers, good thoughts, and whatever else of that nature that y'all can send our way.
